Diane Keaton is selling affordable wine with screwcaps

Last year, Diane Keatontold us that her idea of perfect happiness is “a glass of red wine with ice.” And she wasn’t kidding.

Earlier this week, our favorite eccentric Oscar winner debuted her very own affordable bottle of red wine—“The Keaton”—which features one instruction on its un-fussy label: “Must serve on ice.”

How did this fancy Hollywood actress get hooked on iced reds?

“I think most likely since it was so hot in N.Y. when I lived there in the ‘70s,” Keaton tells People. “I used to go on the balcony to cool down since my apartment didn’t have A.C. and one day I thought about trying it on ice. It has stuck ever since then!”
